Prof. Products Intake Manifold...

Not very good. Flows a LOT. Too much for a mildly modded motor. I've also heard that it will need slight machining to get the burrs etc. out of it. Also, check the fuel injector bungs, which may not be that exacting.

Honestly, i'm thinking of buying one myself due to the price and the higher flow, but i have a turbo.
 
The lower isn't the greatest machined peice I've seen. That large coolant bung is easily stripped. The Edelbrock lower is far more superior. Any thread on the PPI is pretty crappy. When installed though it works nicely. If there were moving parts in there I would really pass. There throttle bodies are total garbage. Avoid those as they've had problems for years with them.
 
The PP intakes are both :nice: and :notnice:, but it seems to vary from person to person. Mine looked very nice out of the box, and has almost no casting flash to remove in the injector bosses, although the ports leave a little to be desired. That in itself doesn't bother me however, because I'm going to port match it, as I would with any intake. I know someone else will come in here with horror stories as to all of the work their intake required, but mine earned a :nice:
 
DO not mismatch this intake with your heads and cam

if your cam isnt peaking 5800+ you dont need this and would be better off with a ported cobra or edelbrock.

I have this intake, it works great but as being similar with the edelbrock rpm... if you wouldnt run an rpm on your car, dont run this on yours.

one would be stupid to run this on stock heads purposefully.

I run this intake, it works great. If you are porting the lower anyways, or porting the lower, I woudl pick this up over the edelbrock for pure price. If you want to rev even higher, AFM sells a ported shortened version called the twister which makes good power.
 
If the quality is the same as the elbow they sell...that thing must have been sand cast by a 4yr old who made the cast out of the clay from his rice patty that was just drained and still full of poop.

I realy didnt mind as I planned on sanding/grinding on it anyway (the reason I bought it) but damn that things inner part is rough and un-even, the mounting flanges are all too big, and very rough edges, the tps would not fit unless I ground the crap out of the flange to get it to fit, No install instr. with an odd number of bolts.

I have a solid 3-4hrs of work grinding/sanding/re-working things on mine. I have heard of issues of the upper back plate on the intakes not fitting and sealing correctly and needing a mill.
 
i picked this intake up locally for $240 Canadian.

the casting was pretty clean. nothing major. i'm port matching it anyways.

if your on a budget i dont see why this intake wouldnt be an option. mine must have been a newer version because i heared horror stories on the older ones.

one word of advise, if you want it polished. dont be cheap. buy the already polished one. i'm polishing my satin intake and its alot more work then polishing a stock fox intake. rough casting

i also picked up a polished FOX 70mm throttlebody from the same person for $80 canadian. i beleive the throttlebody problem are mostly on the sn95 style TB's
 
Have a PP Intake and thier 70mm throttle body/EGR. Both work PERFECT with no problems. I spent about $450 for the whole setup.. $$ worth spent to me.

The ports aren't the greatest but I wouldnt say they would noticably affect horsepower unless you are extracting out every OUNCE of power.
 
Well, The main reason i'd be getting it isn't the price. I'm gunna get whatever intake I get ported anyway.. And I'd want it polished just for the bling factor. I don't wanna spend $84849593400493.99 on it though, just something decent because I plan on putting GT-40 heads on and a cam in the future, I'm just undecided on the cam/intake right now.

P.S. Updated my sig.
